Making mobs angry at everyone

So my goal is to summon iron golems with a certain tag, and these golems will be angry at everymob. What have right know is : I summon the iron golems execute at @p[tag=pending_action] run summon iron_golem ^2 ^ ^ {Tags:["summoned"]} then, in tick : execute as @e[tag=summoned] at @s run data modify entity @s AngryAt set from entity @n[type=!player, tag=!summoned, distance=..30] UUID But for some reasons I don't really understand, after killing a mob, they kinda stay stuck and don't do anything
